Question

Give a medal and fan to first that answers
What is the value of y in the solution to the following system of equations?

5x - 3y = -3
2x - 6y = -6

Answer 1

i think it is 2

Answer 2

multiply the first equation across by \(-2\) get
\[-10x+6y=6\]\[2x-6y=-6\] then add the equations to get
\[-8x=0\] so \(x=0\)

Answer 3

if \(x=0\) then you get \(-3y=-3\) so \(y=1\)

Answer 4

ok thank's
